Pressure Control Limits

Word

Description

TOC41

Pressure Minimum Control Limit [02] Minimum controllable clamp pressure attainable during any Press/Pos Third Clamp Open
Profile. The module expects this clamp pressure when setting its selected pressure valve to the %-output in TOC43.

TOC42

Pressure Maximum Control Limit [02] Maximum controllable clamp pressure attainable during any Press/Pos Third Clamp Open
Profile. The module expects this clamp pressure when setting its selected pressure valve to the %-output in TOC44.

TOC43

Selected Pressure Valve Output for Minimum [19] 0% CV output percentage that the module uses to drive the selected pressure
valve during any Press/Pos Third Clamp Open Profile. The module expects a pressure equal to TOC41 when setting the selected
pressure valve to this %-output during profile execution. The Press/Pos Third Clamp Open Profile will be executed as a reverse-act-
ing algorithm if this entry is greater than TOC44.

TOC44

Selected Pressure Valve Output for Maximum [19] 100% CV output percentage that the module uses to drive the selected pressure
valve during any Press/Pos Third Clamp Open Profile. The module expects a pressure equal to TOC42 when setting the selected
pressure valve to this %-output during profile execution. The Press/Pos Third Clamp Open Profile will be executed as a reverse-act-
ing algorithm if this entry is less than TOC43.

Velocity Control Limits

Word

Description

TOC45

Velocity Minimum Control Limit [08] Minimum controllable clamp velocity attainable during any Vel/Pos Third Clamp Open Profile.
The module expects this clamp velocity when setting its selected velocity valve to the %-output in TOC47.

TOC46

Velocity Maximum Control Limit [08] Maximum controllable clamp velocity attainable during any Vel/Pos Third Clamp Open Profile.
The module expects this clamp velocity when setting its selected velocity valve to the %-output in TOC48.

TOC47

Selected Velocity Valve Output for Minimum [19] 0% CV output percentage that the module uses to drive the selected velocity valve
during any Vel/Pos Third Clamp Open Profile. The module expects a velocity equal to TOC45 when setting the selected velocity
valve to this %-output during profile execution. The Vel/Pos Third Clamp Open Profile will be executed as a reverse-acting algorithm
if this entry is greater than TOC48.

TOC48

Selected Velocity Valve Output for Maximum [19] 100% CV output percentage that the module uses to drive the selected velocity
valve during any Vel/Pos Third Clamp Open Profile. The module expects a velocity equal to TOC46 when setting the selected veloc-
ity valve to this %-output during profile execution. The Vel/Pos Third Clamp Open Profile will be executed as a reverse-acting algo-
rithm if this entry is less than TOC47.

Profile Tuning Constants

Word

Description

TOC49

Proportional Gain for Pressure Control [30]

TOC50

Integral Gain for Pressure Control [27] or [28]

TOC51

Derivative Gain for Pressure Control [26] or [21]

TOC52

Proportional Gain for Velocity Control [28]

TOC53

Feed Forward Gain for Velocity Control [30]

Profile Pressure Alarm Setpoint

Word

Description

TOC57

Profile High Pressure Alarm Setpoint [02] The module compares real-time clamp pressure against this entry when executing the
Third Clamp Open Profile. The module sets alarm status bit SYS06-B11 when clamp pressure equals or exceeds this entry during
the Third Clamp Open Profile. A zero entry inhibits SYS06-B11.
